To all whom it may concern: vided with thirty-eight keys arranged. in four Be it known that I, WALTER H. IIANSON', a banks, thereby providing for seventy six citizen of the United States, and a resident of characters; but I have illustrated, as stated, Milwaukee, in the county of Milwaukee and a machine provided with only one-half of the 55 State of Visconsin,have invent-edcertain new usual number of type-keys to avoid useless and useful Improvements in Type-Writers; duplication of parts in the drawings. and I do hereby declare that the following is D represents the spacer-bar; E, the shift a full, clear, and exact description thereof. key; F, the platen-raising key, and G a key My invention relates to the class of typecalled for the sake of brevity the "margin- 6o 1o writing machines which employ keyboards, key, the construction, arrangement, and

the levers C D', and each lever E' and F' is connected by a spiral retracting-spring h' to the keyboard proper, t', while the other levers C' D' are retracted by means of flat springs j', whose free forward ends rest on the base of the frame A, all as shown in Fig. l with respect to the levers C' E', the springs of the other levers F D' (not shown in said ligure) being identical in construction and arrangement.

L represents the ribbon, whose ends are wound around the spools N' O", and M' is what I term the ribbon-holder, whose construction and arrangement are shown in detail in Figs. 1, 3, and 5 and are as follows: The yoke-shaped cross-piece K has at its center two upward lugs b l), perforated to form bearings for the pivot c, passed therethrough, and on this pivot c, between the said lugs ZJ l), there is mounted a sleeve CZ, which forms the center of a bell-crank lever ef, and from the upper arm c of the said bell-crank lever there projects the said ribbon-holder M', the same havingv two pairs of tongues or forks, between which the ribbon L' is held, as clearly shown in' the three figures of the drawings just named, said ribbon also passing around vertical antifrictionssleeves g g, which revolve on studs or pinsjj, projecting up from the top of the said cross-piece K, at about the ends of the straight central portion thereof, as best shown in Fig. 5, from which points the said ribbon goes directly to the said ribbon-spools N' O'. The ribbon-holder M' is kept normally away from contact with the platen J (or the sheet of paper thereon) and retracted (after it has been carried back to such con- -tact by a type-bar, as hereinafter explained) -by means of a spring K, secured to the front end of the lower arm f of the described bellcrank lever and to a pin m, projecting from the front center of the described cross-piece K.

P represents an arc-shaped rod, whose ends are held in the upper ends of the long arms Q Q of the bell-crank shift-levers Q q Q q, on which rod P and between said arms Q Q all of the type-bars are pivot-ally arranged, as

These bell-crank levers Q q are pivoted, one on each side, to the side pieces of the upper part B of the frame or casing on the inner sides thereof, as shown by the lugs or bearings n u and pivot-bolts o o, as shown in Fig. 2, the inner heads 0' of said pivot-bolts being shown in said ligure and one of them being also shown in Fig. l, in which last-named View only the left-hand shift-lever or that nearest the shift-key E is shown, and the shift-lever ou this said lefthand side is provided with a retractin g-sprin g P', secured to the arm Q of the lever and to `a pin q', projecting from the inner surface of the left-hand side piece of the said upper frame or casing B, while the movement of both of the shift-levers Q q is limited by stops or pinspp', projecting inwardly from the said side pieces of the frame or casing B, as most clearly shown with reference to the stops on one side in Fig. l, said stops being duplicated on the other side of the said frame or casing.

Q' is a post projecting obliquely forward from near the upper end of the arm Q of each shift-lever Q q, and to the tops of said oblique posts there is secured a transverse bar R, having right-angled ends r extending toward the rearof the machine. This bar may be brazed, screwed, or otherwise secured in position on the upper ends of the said posts Q', this being immaterial so long as the parts are rigidly united together, and, if desired, the said ends r may be formed integrally with the levers Q q and posts Q' and the bar R be sim ply a straight transverse rod.

S S' represent two levers operated by the shift-keyE. The lever S', at itsforward end, is connected directly to the lower end of the shank of said shift-key Eand farther back is bent into a downward rounded curve, as shown at lo', (so as to pass under the described cross-bar b of the levers C' D',) and thence straight on backward to the described trans verse shaft G', to which its enlarged rear end is rigidly secured near one end of said shaft, all as shown in Figs. l and 2, the said rear end being in the form of a sleeve or hub m', through which a pin 'a' is driven into the said shaft G'. R' is a link pivotally connecting the extreme forward end of the short arm q of the bell-crank shift-lever Q q to this said shift-key lever S', just beyond the described curve or bend k in said lever, by the pivots r' s', this said shift-key lever S' being on the left-hand side of the machine in the construction illustrated in the present drawings, because the shift-key E is shown as being on that side. On the opposite side of the machine is the lever S, which, as shown in Fig. 2, only extends as far forward as the end`1 of the short arm q of the lever Q q on that side, to which short arm the said forward end of the lever S is Ypivotall y connected by another link R' and pivots r' s', the rear end of this lever S terminating, like the just-described lever S', in a hub or sleeve m', slipped on the transverse shaft G', adjacent to its other end, and secured in place thereon by a like pin n.

T T T represent the key-levers, connected at their forward ends to the lower ends of the shanks of the type-keys C C C and at their rear ends terminating in sleeves or hubs 1f t which are slipped on the described transverse shaft G between the sleeves or hubs m' m of the shift-key levers S S'. One of these keylevers/T is shown in detail in Fig. l, where the front straight part bears said referenceletter T, there being a curved upwardly and rearwardly extending intermediate part s and a straight oblique downward rear part t', terminating in the described sleeve or hub t. The straight forward part of each key-lever T rests on the described front cross-bar h' of the levers C' D'.

U U U represent the type-bars, and one of the same is also fully illustrated in Fig. 1. Each type-bar is, near its lower end, slightly IIO .enlarged and there provided with a transverse opening, (whereby the said type bars are strung upon the hereinbefore named arcshaped rod P,) and beyond this the said typebar terminates in an obliquely-disposed foot a, which latter is pivotally connected, by a link T', to its key-lever T, the upper pivot being shown at u', at the end of the foot a, and the lower pivot being shown at c', at the apex of the upward-extending portions s and t' of the key-lever T. The upper free end of the type-bar U is bent rearwardly and upwardly and fitted with a plate U', bearing two characters, one above the other, the faces of the said characters slanting in opposite directions, as shown in Fig. l. These typebars U U are all strung on the rod P, andthe object in having the said rod arc-shaped is so that each type-bar will strike at exactly the same place-viz., through the front center of the ribbon-holder M, between the front fork or front pair of tongues thereof, as indicated by the broken or dotted lines in Fig. 3.

V is a transverse rod extending across the front portion of the machine from side to side of the upper frame or casing B just back of the front portion of said frame or casing, and V represents a spiral retracting-spring whose upper end is secured to said rod V and whose lower end is secured to a loop or eye/U on the key-lever T beneath, there being one of these i lever may be instantly retracted to its normal position after it has been depressed. One of these springs, with the rod V in section, is shown in Fig. l; but this showing is omitted in Fig. 2, together with the series of type-bars U U, to avoid confusion in the drawing,which simply shows at this place the` key-levers T T and portions of connected mechanism.

The preferred arrangement of characters on the plates U of the type-bars U is that common to type-writing machines which employ a shift-viz., the upper character is the capital letter and the lower character is the corresponding lower-case letter, with the usual arrangement of figures and punctuation-marks, &c.-and I lay no claim to that arrangement; but, so far as I know, making the faces of the upper and lower characters on each plate slant in opposite directions is new with me, the object being to have each character at its im pactwith the ribbon (when the latter is against the paper on the platen) stand exactly vertical and give a direct horizontal impression, whether the type-bar is in its normal position, so that the lower character will strike, orshifted, so that the upper character will strike. It is sometimes desirable to continuously use the u pperl characters exclusively for an extended length of time, as in making headings of letters or circulars, duc., and to facilitate this I employ the shiftlever lock. (Shown best in the detail view, Fig. l2.) The locking-cani of this device is also shown in Fig. l; but in Fig. 2 I have omitted any showing of this device, which would otherwise confuse the view of the shiftlever Q q on the left-hand side of the machine.

W represents thelocking-cam of the shiftlever lock, which cam is castrigidly with a sleeve or collar w, these parts being located on the inner side of the left-hand side piece of the upper frame or casing B, so that the said cam is in vertical line with the short arm q of the shift-lever Q q on that side, said part W w being made rigid, as by pin with the inner projecting end of a shaft X, which is journaled in said side piece of the frame B, while W represents a finger, having a sleeve or collar w rigid therewith, mounted on the outer projecting end of said shaft X and there secured, as by pin zr', all as best shown in the said detail view Fig. 12, the cam W and finger Wl of the device projecting at practically right angles to each other, so that by pulling on the finger W and drawing it forward from a practically vertical to a practically horizontal position the said locking-cam W will bear down on the short arm q of the shift-lever Q q on that side, shiftingsaid lever against the force of its spring P, and thereby not only accomplish the shift without the need of touching the shift-key E, but also lock the lever in the shifted position, (shown in dotted lines in Fig. 1,) while a downward push against the said linger W will serve to instantly free the point of the cam W from contact with the arm q, thereby allowing the said spring P to retract the shift-lever to its normal position (shown in full lines in Fig. l) and restoring the parts to their normal condition.

The platen J consists of a hollow cylinder of india-rubber mounted upon a hollow cylinder X,of either wood or metal, but preferably of the former for lightness. Y is a circular base-piece formed with a vertical central tube Y', extending upwardly to a height greater than that of thesaid cylinder X and platen J, said tube being externally round-in crosssection and having a bore which is square in cross-section, said tube further extending below the base-piece Y a short distance,as shown at y, while from the upper surface of said base-piece there projects an annular flange y', which may be formed with exterior screwthreads to take into or engage with the lower end of the cylinder X.

Z is an annular plate or iiat ring surrounding the annular iiange y and resting on the outer circumferential portion of the basepiece Y, said ring Z having a circumferential shoulder formed by an upward vertical ann'ular iiange terminating in an outward horizontal iiange, as shown at z', leaving thereby an annular space all around between the basepiece Y and flange .e for the reception of another llat ring Z', from whose periphery 'there IOO IIO

projects horizontally a pin a, for a purpose said cap having a downward-depending annular flange a2, corresponding to the flange y' of the base Y, which flange on the cap is preferably exteriorly screw-threaded to take into or engage with the upper end of the cylinder X', and between the top of said cylinder and the under surface of the outer circumferential portion of the cap there is located an annular plate or flat rin g B2, which is the counterpart of the described lower ring Z, only applied in a reversed position, the upper ring B2 having a circumferential shoulder formed by a downward vertical flange terminating in an outward horizontal flange, as shown at b2, thus leaving an annular space all around between the said flange b2 and cap A2 for the reception of another flat ring C2, which latter corresponds to the described lower flat ring Z', and the two last-named flat rings are united by a vertical rod c2, and in the preferred construc- 'tion before both of the said flat rings are united to the ends of the rod c2 there are slipped upon the latter the open annular paper clamps D2 D2. The preferred form of these clamps is best shown in Fig. 5, wherein is illustrated one of said clamps formed of a flat metallic spring-band open at one point, said band being enlarged and vertically perforated, as shown at d2, to receive the rod o2, (although, of course, a separate loop could be secured to the band D2 for this purpose, if desired,) and at suitable intervals the said band is similarly enlarged and is vertically perforated and transversely slotted for the reception of rollers e2 e2 of any suitable number, (five being enough for effective service,) which rollers bear against the sheet of paper E2, (shown by a solid black line in Fig. 5,) which is wrapped around the platen J to be type-written upon and hold the paper in place by frictional contact, one end f2 of the band D2 being bent inward, so as also to bear against the paper. The rod c2 is stationary; but adjacent thereto there is another rod g2, whose ends are journaled in the described flat rings O2 Z' and which rod is covered with a tight-fitting rubber cylinder h2, which also bears against the paper E2, the band D2 being curved around the cylinder h2, but free from contact therewith, as shown at 2, beyond which point the adjacent end of the said band is bent to project outwardly, as shown at j2.

In Fig. l I show how the platen J and its cylinder X are secured in place between the base-piece Y andcap A2, with the intermediate flat rings thereby securely clamped in position, it being preferable that there should be a collar 7a2 near the upper end of the tube Y', against which collar the under surface of the cap A2 abuts, the upper end of said tube passing through a central opening in the upper cross-bar K' of the platen-su pportin g slide H' I', while the described lower end y of said tube Y' is seated in a central opening in the lower cross-bar J of said slide. The upper end of the tube Y' is preferably formed with screw-threads on its outer surface for the ready attachment thereto (after the parts have been put together as shown and described) of a hand-wheel F2 for the more convenient manipulation of the platen, as hereinafter described.

G2 is an obliquely-disposed horizontal arm projecting inwardly from the left-hand standard H toward the platen J and provided at its inner end with a downwardly-projecting pin m2 for engagement at the proper time with the horizontally-extending pin e' on the periphery of the lower flat ring Z' of the platen when the paper is to be fed on said platen, as hereinafter set forth.

H2 represents the platen-raising lever, connected at its front end to the platen-raising key F and terminating at its rear end in an enlarged hub n2, whereby it is mounted on the transverse shaft B' at the rear end of the machine, next to the hub or enlarged rear end d' of the lever D', there being an upwardcurved bend o2 near its rear end to enable said lever H2 to pass over and operate free from contact with the shaft K2 of the ribbon-reversing mechanism, hereinafter described. I2 is a Hat spring secured at its front end to said lever H2 and with its free rear end resting on the upper surface of the base of the frame A of the machine. J2 represents the marginkey lever, connected at its front end to the margin-key G and extending backward substantially in horizontal line with and just beyond or on a line inside of the said lever H2. The lever J2 terminates at its rear end in an enlarged hub p2, whereby it is mounted on the aforesaid rear transverse shaft B', between the hub a2 of lever H2 and the adjacent lug A', and is, furthermore, formed with an upward-curved bend q2 near its rear end, like lever H2, (there being also a like upwardcurved bend r2 in lever Dl at this point,) to

`enable all these levers to pass over and escape contact with the aforesaid shaft K2. L2 is a fl at spring (similar to the j ust-described spring I2) secured at its front end to said lever J2 and with its free rear end resting on the upper surface of the base A, exactly like said spring I2. The lever J2 is further provided with a lug s2, projecting from its upper surface and transversely bored to form a bearing for a rod M2, hereinafter described, the adjacent projecting end of said rod resting on top of the platen-raising lever H2.

Referring now especially to Figs. 3, il, 5, 6, and 7, I will next describe certain details of the line-spacing mechanism. The side bar I' of the vertical platen-supporting slide, which moves in the slot t' of standard I, is provided on its outer transverse edge with a series of notches formed by teeth 152 t2 152, projecting beyond the edge of said standard I. N2 O2 represent the arms of an L-shaped lever, the

arm O2 of which is perforated and journaled IOC on a pivot-bolt u2, which is screwed into a lug 122 on the rear of the standard I, this arm O2 screw x2, which projects vertically through the screw-threaded bore of a lug {1/2 on said standard l. At about the angle of the two arms O2 N2 of this lever there is a perforated lug z2, from which a spring P2 extends to a pin or lug a3 on the standard I. The arm N2 of this lever is provided with a pin or stop b3. These two arms N2 O2 are laterally or horizontally disposed. Q2 R2 represent, respectively, the upright and lateral arms of another L-shaped lever pivotally secured atabout the junction of the said two arms thereof to the arm N2 of the first-named lever, the pivot in question being the properly-shouldered shank c2 of a finger S2, the said lever Q2 R2 having a heel d2, which comes normally against the hereinbefore-named pin or stop b3, while to the outer end of the lateral arm R2 of said lever there is connected the upper end of a link T2, whose lowerend is pivotally connected to the hereinbefore-named platenraising lever H2, as shown at e3in Fig. 4. U2

represents the head of a cam, having a suitable lever-handle f3, said cam being pivotally secured to the said lever Q2 R2 by means of the properly-shouldered shank of a pivot-bolt g3. The lever-arm Q2 has a lug 7t3projecting therefrom, to which is secured the upper end of a curved flat spring V2, whose free lower end bears against the head of the cam U2. The upper end of the lever-arm Q2 terminates on one side in an inwardly-bent stationary dog i2, which in the position of the parts shown in the drawings is understood as being in engagement with one of the notches or teeth 152 ,on the side bar I of the platen-supporting slide.

W2 is asliding plate having avertical slot 7c3 therein, through which slot there pass the shanks of headed screws m2 m2 into the lever-arm Q2, so that said plate has free vertical movement betweenthe -heads of said screws and. the outer face of said lever-arm,

' the said slide W2 resting, when it drops by its own gravity, on. the head'of the cam U2 and the upper end of said slide terminating in another inwardly-bent dog jg of like shape with the described dog i2 and disposed at the right-hand side thereof, so that when the lever Q2 R2 is pulled to the left by the link T2 and lever H2, as hereinafter explained, the dog z2 will be laterally freed from engagement with a notch or toot-h 'f2 of the slide side bar I and the dog ,7'3 be brought into engagement with the same notch or tooth. y

Referring now particularly to the detail views Figs. b, 9, and lO and also to Figs. 2 and 3, I will next describe certain details of the letter-spacing mechanism. X2 is a cross-piece which connects the two standards H l at some little distance above their lower ends, and the mechanism about to be described is mainly situated adjacentt o the left hand standard below this cross-piece, the said cross-piece being provided with a central vertically-perforated hub n3 to form a bearing for the hereinafter-described vertical shaft, which serves to revolve the platen. Y2 is a vertical plate projecting inwardly from the standard I-I just beneath the cross-piece X2, to which it may be cast or secured, as shown best in the detail view Fig. 9. Z2 is a horizontal plate or table projecting from the rear of the standard H aty a plane below the bottom of the plate Y2 and extending inward at a right angle, said table having a downward-depending vertical flange or web o3 along its inner edge and anarm 193 projecting horizontally from its outer edge and thence extending vertically and terminating in a perforated bearing g3 for a pushrod A3, which latter is provided with a notch w3 thereinto engage with a latch x3 secured by pivot g/ to said arm p3, as hereinafter described.

B3 represents a stop-arm the lower end of which is rigidly fastened to a shaft r3, journaled in the lower inner corner of the described plate Y2, to the other end ofn which shaft, beyond said plate, there is rigidly secured a fork C3, which straddles a pin lD3, proj ecting from a'sliding plate E3, which has longitudinal movement on the table Z2 by reason of a slot s3 in said plate and the Shanks of headed screws t3 752, passed through said slot into said table Z2.

F3 represents a segment having a hub a3 cast rigidly on one side thereof, said segment being pivoted to the flange o3 of the table z2 by a pivot o2. The upper end of this segment is formed with a fork w3, which straddles the described pin D3 just back of the fork C3, and the lower rounded edge of said segment is provided with two notches or indentations :r3 @/3 for engagement at the proper time, as hereinafter explained, with a dog z3 near the free outer end of a at spring G2, whose inner end is secured to a lug a4, projecting from the standard H. Further, the said segment F3 is provided with two shouldered pins h4 c4 for engagement with the loops d4 e4, respectively, of the links H3 I2, as hereinafter explained.

J 3 is an angle-block whose lower horizontal part rests on the inner end of the described sliding plate E3, to which it is pivotally secured by screw-bolt f4, while the upper vertical part has a rearward-projecting lug g4, to which is secured one'end of a retracting-spring K3, whose other end is secured to a lug h4, projecting rearwardly and upwardly from the slide E2. The outer end of this lug h4 is transversely perforated to admit the passage therethrough of the hereinbefore-named push-rod A2. Just back of the angle-block J 3 there is a vertical lug or stop i4 on the upper surface of the slide E3, at the inner rear corner thereof. L2 is a lever which is pivotally secured to 'the vertical upper arm of the angle-block J 3 right angle to the length of said lever and ofv about half the width thereof. The other end m4 of said lever is adapted to be engaged by the inner end of the described push-rod A3.

M3 is a sliding plate having a longitudinal slot n4 therein, whereby it is secured to said IOO IIO

lever L3 by the shanks of headed screws o4 o4, 'passing therethrough into the lever, and said plate terminates at its forward end in a like bent dog p4 of the same width and projection as that of the described stationary dog Irion the lever L3. The said lever is further formed v with a downward extension g4, from which there projects a lug r4, and to `this lug there is secured the lower end of a ilat spring s4, whose upper free end bears against the reari end of the said sliding plate M3. S N3 is a headed pin projecting from the le-` ver L3, and from said pin the link H3 is sus-` pended by means of a ring or eye i4 at the; upper end a4 of said linkabove and at a right! angle to the loop d4 in said link H3. Referring especially to Figs. 1, 2, and and incidentally to Figs. 9 and l0, O3 repre; sents a horizontally-disposed wheel having al notched or toothed periphery for engagement-1. with the just-described dogs etplon the lever L3 and its sliding plate M3. The wheel O3 is vmounted near the lower end of a verticali shaft P3 and rigidly secured to said shaft, lwhich latter has a cylindrical lower end passi ling through the central vertical bore 'n3 in the hereinbefore-named cross-piece X3, there be- `ing a collar U4 rigidly secured to said shaft just above the said cross-piece X3, on which; the said collar restsfand above this collar the said `vertical shaft P3 is square in cross-sec-y tion, so as to t within the square bore in the? vertical central tube Y' of the platen J. The Wheel -03 has a hub 1.04 on its under side, and below this there is a pulley Q3, rigidly secured i to the extremelower end of said shaft P3. In. the drawings the pulley Q3 is represented as having a concave or V-shaped groove in its; periphery for the reception of a triangular1i belt R3, passing around a like groove in the periphery of another and larger pulley S3 at the rear of the pulley Q3, as hereinafter de-g scribed; but it is obvious that., if desired, the said two pulleys may be belted together in `any other way, as by asprocket-chain engaging with sprockets on their peripheries, orr they may be connected by a train of gear?` wheels instead of by the friction-belt shown.

T3 is a Wheel horizontally mounted on the shaft P3,the hub m4 of said wheel coming justv below the crosspiece X2 and the rim if of said wheel being of greater thickness than?y vthat of the web of the wheel and square in. cross-section, as shown in Figs. land 9, so as to best provide for the attachment to said rim of the margin-regulator U3, consisting of upper and lower plates with opposed recesses` in their rear ends to embrace the said Wheelrim @/4 and a clamping-screw .e4 to draw these two plates together and secure them tightlyY to the rim at any required point on said wheelrim, according to the width of margin desired to be maintained on the left-hand side of the sheet type-written upon, this being accomplished by the stoppage of said margin-regulator vby the stop-arm B3 at the proper time, as hereinafter explained.

V3 represents a lever whose rear end terminates in an enlarged hub a5, loosely mounted on the hereinbefore-named transverse shaft B at the extreme rear end of the machine and whose front end is rigidly connect-ed to the adjacent end of the rod M3, whose other end is journaled in the margin-key lever J3. This lever V3 is formed with an upwardcurved bend b3 (best shown in Fig. 3) to enable it to pass over and escape contact with the hereinbefore-named shaft K2, and said lever is supported near its forward end by the link I3 from pin c4 on segment F3, as shown in Figs. 3 and 9.

W3 represents a lever whose rear end terminates in an enlarged hub c3, mounted on the transverse shaft B', next to the hub a3 of lever V3; but unlike that this hub c3 is rigidly secured to said transverse shaft, so that la right-hand standard, atlthe rear end of the machine, said standards being connected at their tops by a transverse cross-bar Z3, said standards having outwardly-projecting feet e3f5, secured to the upper surface of the bottom of the base A of the machine, as by screws or rivets g3 g5. A short distance above its foot c3 the standard X3 has a horizontal outward-projecting arm h3, provided with a vertical bore therethrough, forming a bearing for thevertical shaft N of the ribbon-spool N, already described, and, similarly, the standard Y3 is provided a correspon ding short distance above its foot f3 with a horizontal outwardprojecting arm i3, provided with a vertical bore therethrough, forming a bearing for the vertical shaft O of the other ribbon-spool O'. The described transverse shaft K2 passes through holes or bearings in said standards X3 Y3 about midway between the said feet and outward-projecting arms, which latter form a casing or housing for the outer vertical miterwheels k3 on the shaft K2 and for the horizontal miter-Wheels n3 o5 on the lower projecting ends of the vertical shafts N O. The transverse shaft K2 is provided with a head m3 to facilitate moving said shaft in or out to enable its vertical miter-wheels to engage with one or the other of the adjacent horizontal miter-wheels, as hereinafter described. The said shafts N O are kept at their proper elevation by means of collars p3 Q5, secured to them and resting upon the rearward-extending arms L M.

A4 represents another cross-bar connecting the j ust-described rear standards X3 Y3 in line with and below the cross-bar Z3 about midway of the height of said standards. The upper cross-bar Z3 is provided with a central ver- IOS IIO

tically-perforated hub rs, and the lower crossbarA4 is similarly provided with a central vertically-perforated hub S5, both forming bearings for a vertical shaft B4. C4 is a handwheel on the projecting top end of this shaft B4, just below which there is a ratchet-wheel D4, which latter is rigidly secured to said shaft just above the cross-bar Z3.

E4 is a horizontally-disposed escapement, which is pivoted, as shown at t5, to the crossbar Z3 and held in engagement with the teeth of the ratchet-wheel D4 by a spring F4, secured to said cross-bar, the lever of said escapement being marked a5.

G4 is a horiZontally-arranged hollow or shell pulley within which is contained a` volute spring I'I4, properly secured at its ends within the shell of the pulley and covered with a top or casing p5, as shown in Fig. l, said top or casing being removed or broken away in Fig. 2 to show the said spring H4. The periphery of this pulley G4 is grooved to hold the cord I4 as it is wound thereon, one end of said cord being secured to the said pulley,

as shown at n4, Fig. l, and said cord I4 thence passing obliqnely to and under a pullej7 J4, secured toa stud won the forward obliquelyprojecting` end of a V- shaped lug K4, extending from the left-hand standard l-I. From this pulley J4 the said cord I4 extends vertically upward to, over, and around a pulley L4, mounted on an inward-projecting stud m3 on a curved lug M4, projecting from the top of the standard II above the yoke-shaped cross-piece K, 'while the pulley J4 is located on a horizontal line just above that of the shell-pulley G4. over the upper pulley L4 from the rear side thereof continues down on the front side of said pulley to a lug N4 on the left-hand end of the lower cross-bar J of the platen-supporting slide and is there secured, as best shown in Fig. 3.

Just below the described shell-pulley G4 the vertical shaft B4 is provided with another ratchet-wheel O4, whose hub z5 abuts against the under side of the depending hub ot' said shell-pulley G4 and is fastened to the said vertical shaft. From the under side of the justnamed shell-pulley there depends a lug or arm a6, which is rigidly connected to said pulley, and to the lower end of this arm there is secured by pivot-bolt b a dog or pawl P4,

whose free end engages with the teeth of the ratchet-wheel O4. A vertical pin c4' rises from the upper surface of said dog or pawl P4, and a flat spring d4 projects from the said arm a4 and bears against said pin to keep it against said ratchet-wheel O4. The said shaft B4 is further provided with a collar c, rigidly secured thereto and resting on the hub s3 of the cross-bar A4, and just below said crossbar is located the hereinbefore-named horizontally-arranged pulley S3. This is also a hollow or shell pulley with a top casing f, and it contains another volute spring Q4, secured therein, so as to operate in exactly the The cord I4 after passing up reverse direction from the spring II4 in the shell-pulley G4 above. I have already described the peripheral groove in this shellpulley S3 and the belt R3, traveling therein and around pulley Q3. The lower side ofthe pulley S3 is formed rigidly with a depending hub gs, terminatingin a horizontal ruiter gearwheel h6, which is adapted to meshu with one orthe other of the opposing vertical miterwheels i6 js on the transverse shaft K3, according as the latter is drawn out or pushed in, as hereinafter explained. I

R4 represents a collar at the extreme lower end of the shaft B4, whose function is to keep the pulley S3 and its miter gear-wheel h6 in proper position on said shaft.

Vith respect to the two shell-pulleys and the volute springs therein contained it is to be noticed that one end of the upper volute spring H4is secured to the pulley G4 (preferably to the inner end of the pivot-bolt v5, whose outer end secures the adjacent end of the cord I4, as already described) andthat the otherend of this spring H4 is secured to the hub 715 of the cross-bar Z3, as shown at k6, and hence that said upper volute spring is free from contact with thevertical shaft B4, while one end of the lower volute spring Q4 is directly attached to said shaft B4, as shown at m4, and its other end `is secured to the pulley S3, as clearly shown at a6.

In Fig. l I have shown the bell and adj uncts and omitted the same from the other figures to avoid confusion in the drawings. S4 represents a bell supported on an upright stand.- ard 03, rising from an arm T4, which projects inward from the left-hand side piece of the frame or casing of the machine. rising from the inner end of said arm, this post being shouldered and provided at its upper end with a vertical stationary spindle or journal p3 to form the bearing for the hub q of a bell-crank lever, one arm, r6, of which carries a knob s at its end to impinge against the bell s4, while the other arm, '154, projects in the path of a downward-projecting pin V4 on the wheel T3, (which I term the stop-wheel,) said arm t4 being provided with a` downward bend, as shown at a6, toenable it to escape contact with the hereinbefore-narned marginregulator U3. V4 represents a sprin g secured to the spindle or journal p6 above said bellcrank-lever hub q to engage with an uprightpin n on the arm t of said lever Vto force the knob s against the bell S4 at the proper time.

The operation of my machine will be readily understood from the foregoing description of its construction, taken in connection with the accompanying drawings.

I will first describe the manner of securing the sheet of paper to be type-written upon to the platen J. The said sheet E3 is secured vertically around said platen, as indicated in Figs. 5 and ll. First of all the platen .I is

raised above the plane of the ribbon L, which is done as follows: The operator places his left hand on the hand-wheel F2 on top of the IOO [IOv

tube Y' (so as to regulate the speed with which the platen is raised) and with his right hand presses down on the finger S2, and thereby releases the dog t2 from contact with the engaging notch or tooth t2 of the side bar I' of the platen-supporting slide, when the said slide will be automatically raised by the'action of the spring H4 within the shell-pulley G4, said spring causing said pulley to rapidly revolve, thereby winding the cord I4 around its periphery and raising the platen. When the platen is raised to the proper height, the operator withdraws his hand fromthe said nger S2, when the spring P2 draws The leverarm Q2 inward on its pivot-bolt u2 and causes the said dog z2 to again engage with a notch or tooth t2 and hold the platen-supporting slide in its raised position. The operator next presents the right-hand vertical edge of the sheet of paper E2 against the platen J back of the outwardly-projectin g ends j2 of the described open annular paper-clamps D2 D2, holding the sheet E2 in his left hand, and with his right hand revolves the platen by means of the hand-wheel F2 just named, the said clamps D2 D2 being adjusted at the proper distance apart, according to the height of the sheet of paper, these clam ps being held in any adjusted position (to which they have been moved on the vertical rod c2 by hand) by frictional contact of the spring-bands of said clalnps and their rollers e2 e2 against the platen and the said sheet of paper thereon. As the platen is thus revolved by the hand-wheel F2 on the tube Y', which incloses the square vertical shaft P2, the said sheet of paper is next engaged by the described vertical rubber cylinder h2, which thus acts as a feed-roller and draws the paper in around the platen, between the latter and the said rollers e2 c2 on the clamps D2 D2, until the said sheet E2 is firmly secured in place with the other ends f2 of said clamps D2 bearing also on the said sheet, as shown in Fig. 5. The platen J, with the paper in proper position thereon, is then pushed downward by pressure on the said hand-Wheel F2 to the proper position, so that the upper part of the sheet, on which the first line is to be type-written, will be in line with the ribbon L'. The type-keys G are struck in the ordinary way, and as each key C is depressed (against the force of its retractingspring V') it carries down with it the forward end of its lever T, whose rear end is pivoted on the transverse shaft G', and this downward movement of the key-lever T draws down its link T', and as the other end of said link is pivoted to the oblique foot u of the corresponding type-bar U (pivoted on the arc-shaped rod P) the free upper end of said type-bar is thereby thrown over toward the platen, and the character-bearing plate U' on said end of the type-bar is thus carried between the front pair of tongues of the ribbonholder M' and against the ribbon L', thereby forcing said ribbon and ribbon-holder against the sheet of paper on said platen, (against the force of the spring k of the said ribbon-holder,) making the desired impression. As the operators finger is removed from the type-key just struck the retracting-spring V' carries the key-lever T back to its normal position, and the retracting-spring k performs a like office for the ribbon-holder M'. The shift when the upper character on the plate U' of the type-bar is to be impressed is accomplished as follows: The operator with his left hand depresses the shift-key E, which depresses the forward end of the shift-key lever S' on the left-hand side of the machine, whose rear end is rigidly secured to the transverse shaft G', as already described, and this movement draws down the link R' and the short arm Q of the shift-lever Q q on said left-hand side of the machine, and the same action takes place with the lever` S, rigidly secured at its rear end to said shaft G' on the righthand side of the machine, and consequently this draws down the link R' and short arm of the shift-lever on said right-hand side sim ultaneously, thus throwing both shift-levers Q q Q q and their posts Q' into the position shown (for the left-hand set) in dotted lines in Fig. l against the force of the spring P'. The arc-shaped rod P, being carried by the long arms Q of the shift-levers, when thus thrown back gives a different center to the arc of the circle through which the characterplate U' of each type-bar U moves in making the impression against the platen from that occupied before making the shift, and hence when the parts have been shifted, as described, the upper part of said plate U' will strike against the ribbon, and in order that the face of the type or character may always strike squarely, as the platen has a vertical face in my machine, I have slanted the upper and lower characters on the plate U' in opposite directions, as already set forth, and I have already described how the shift-lever may be locked to continue the use of the upper characters exclusively when desired and how the retracting-spring P' will restore the parts to normal position after unlocking the same or after shifting a type-bar when the shiftlevers are not locked. The spacer-bar levers E' F'-, as stated, are pivotally attached to the transverse shaft G' at their rear ends like the key-levers T, and the operation of all of these levers E' F' and C C C, &G., is exactly the same. All of these levers rest upon the crossbar b', whose ends are connected to the abruptly-rising forward ends of the described levers C' D'. Now as either the spacer-bar D or one of the type-keys C is depressed this action (through the levers of the spacer-bar or the key-lever) depresses the said cross-bar b', whose levers C' D are rigidly secured at their rear ends to the rear transverse shaft B', and thus partly revolves said shaft B', thus depressing the forward end of the lever W2, -whose rear end is rigidlysecured to said shaft B', as already described, said lever W3 being supported by the link H3, as best shown YOO IIO

in Fig. 9, and said link being connected by its loop d4 to a pin b4 on the segment F3,while the upper-end of said link is secured to a pin N3 on the dog-lever L3, as already described, and the result of this depression of the forward end of the said lever W3 is to pull down (through said link H3) on said dog-lever L3, bringing the stationary dog 7a4 on said lever down out of contact with the toothed or notched horizontal wheel O3, which is fast on the shaft P3 of the platen (which stationary dog 7a4 held said wheel O3 stationary) and` drawing the dog p4 on the sliding plate M3 on said lever L3 into contact with said wheel O3.

The moment the stationary dog 7194 is released from contact with the notched periphery of the wheel O3 and its place taken by the dog p4 on the sliding plate M3 the force of the volute spring Q4 within the shell-pulley S3 will partly revolve the said pulley S3, and the belt R3 in the peripheral groove of pulley S3 will partly revolve the pulley Q3, rigidly secured to the lower end of the shaft P3, until the sliding plate reaches the limit ofits movementton the lever L3., which is a distance equal to just one notch on the periphery of the said horizontal wheel O3, when the Wheel O3 is again brought to astandstill, but meanwhile in the j ust-described movement of the pulley Q3 the attached squared shaft P3 has been partly re'- volved acorresponding distance, thereby carrying the platen J around to present on the sheet E3 the space required for the.impres sion of one character on the plate U' of the type-bar U. The moment the operators finger isremov'ed from the type-key (or spacer-bar) after depressing the same the retractingsprings V or h (as well as the retractingsprings j of the levers C' D') will restore the various levers to their normal positions and turn the transverse shaft B back to its former position, thereby raising the lever W3, freeing the dog p4 from and restoring the station-` ary dog 7a4 to engagement with the notched wheel O3, the said dog 7a4 now occupying, of course, the next notch ahead ofl that which it occupied before the wheel O3 was moved by the movable dog 194, and the latter on its release is moved forward to its former position by the action of the spring s4 against the rear end of the sliding plate M3. WV hen the rst line of type-writing is nearly completed across the sheet E3, the bell S4 gives warning by reason of the contact of the pin V4,Which is on the under side of the stop-wheel T3,with the adjacent arm t of the bell-crank lever, followed immediately by the action of the spring W4 against the pin r3 on said arm,

Ywhen the pin-V4 has moved past the said arm t3, and when the type-written line is completed-say with from seven to ten impressions orimpacts of type-keys after the bellhas sounded, according to the location of the pin V4 on the stop-wheel T3-or as soon after the bell has sounded as is desired within said limits the operator presses the margin-key G,

which depresses the lever J3, and, through thus draws the dog on the end of said lever laterally away from engagement With the notched or toothed wheel O3. This same movement ofthe pin D3 carries the fork C3 back toward the standard H of the machine, and as this fork C3 is rigid with shaft r3 of the stop-arm B3 the said stop-arm B3 is thrown forward in the path of the margin-regulator U3 on the wheel T3, and as the shell-pulley S3 is now no longer held from revolution by the described engagement of one of the dogs on lever L3 and the teeth or notches on wheel O3 the spring Q4 within said pulley S3 is free to revolve the latter, and this, through the belt R3 and pulley Q3, revolves the shaft P3 and with it the stop-wheel T3, rigidly secured to rod which projects over the platen-raisin g lever H3 depresses said lever H3 and draws down on the link T3, and this link pulls down the outer end of the lateral arm -R3 of the L- shaped lever Q3 R3, (see Figs. 6 and 7,) and as said lever is vthus tilted on its pivot c3 the stationary dog 'i3 is moved laterally out of its engagement with a tooth or notch t3 on the side bar I', and the dog j3 on the sliding plate W3is broughtinto engagement with that same tooth or notch, whereupon the action of the spring H4 revolves the pulley G4, winding up the cord I4 in the grooved periphery of said pulley, and thus raising the plate J. This upward movement of the platen is checked when the lower end wall of the slot 7a3 in the sliding plate W3 encounters theshank of thel 'in height'to that of two adjacent teeth or 4notches t3, and then the platen and its paper will be raised a double or two-line distance. The moment the operator removes his finger from the margin-key G the lever H3 is raised by means of its spring L3, and as the link T3 is stiff this link raises the outer end of said arm R3 back to its normal hori- IOO zontal position and throws arm Q2 back from a tilted to its normal vertical position, thereby pushing the sliding-plate dogj3 laterally out of engagement with the notch or tooth it has just occupied or engaged with and pushing the stationary do'g 013 into engagement with the next lower notch or tooth if the camhead U2 is set for a single tooth and line adjustment or the second lower notch or tooth if the cam-head is set for a double-tooth or two-line adjustment. In the previously-clescribed movement of the segment F3 (when the margin-'key G wasdepressed) said segment was tilted over to the left and that side brought down by the link I3, the upper end of the loop e4 of said link being in engagement with the pin c4 and the segment held in this position by engagement of the dog z3 on spring G3 with the'left-hand notch in said segment. At the same time this tilting of the segment F3 has resulted in raising the pin b4 up to the upper end of the loop d4 of link H3, and when the margin-key G is released and the lever H2 is raised by its spring L2, all as stated, the rod M2 is also raised by lever H2 and with it the lever V3, fast on the other end of said rod M2, and this upward movement of the lever V3 raises the link I3, the lower end of the loop e4 being now in contact with the pinc4, the relative positions of loop d4 and pin h4 being unchanged from the last-described relations.

The effect of the foregoing-described movements consequent upon the depression and subsequent release of the margin-key G is practically to revolve and raise the platen, so as to carry the paper fast thereon around to the point where the next line is to be started, so that the paper on the platen is in position to receive the impact of the first letter or character on said new line. The first type-key C struck (or iirst striking of the spacer-bar D if that is to be now first used) will depress cross-barb' and levers C' D', turning the rear transverse shaft B', and hence depressing the forward end oflever W3,(whose hub c5 is rigidly secured to said shaft B',) which draws down on link H3, and thereby (as the top of the loop d* of said link is now against the pin h4) drawing down the elevated righthand end of segment F3, whose fork w3 moves the pin D3 away from the standard H, carrying with it the slide E3 and attached lever L3, thus bringing the dog p on the sliding plate M3 into engagement with a notch or tooth on the wheel O3, (spring Q4 now being permitted to revolve pulley S3, and thus move wheel O3 one notch,) and this movement of the pin D3 will also carry the fork C3 with it away from the standard H, and thus cause the stop-arm B3 to recede from the path of the marginregulator U3. This movement of the segment F3 causes the left-hand side of said segment to rise, carrying the pin c4 up against the top of the loop e4 of link 13 and also causes the dog .e3 011 spring G3 to escape from notch m3 and engage with the right-hand notch @/3 of the segment. The moment the operators finger is removed from the said j ust-struck type-key C (or'spacer-bar D) the levers C D are raised by their springs j', thereby revolving rear transverse shaft B back to its normal position, and thus raising lever W3 to its normal position, and this in turn elevates link H3 to its normal position, with the lower end of its loop d4 against pin b4, and said upward movement of lever W3 and link H3 also raises the adjacent end of the lever L3 (on its pivot li4) by reason of the pin N3 on said lever and ring or eye t4 at the top of the upper end a4 of said link H3, which elevates the dog p4 on sliding plate M3 above and free from the wheel O3 and causes the stationary dog kt on said lever L3 to engage with the notch or tooth on the wheel O3 next to the one just vacated by the sliding-plate dog p4, the several parts being now all in the relative positions best shownv in Fig. 9.

It only remains to describe the especial function of the platen-raising key F. The platen-raising lever H2 has been described, with the manner in which it was operatedjby the margin-,key G; butit may also be operated directly by its own key F independently of the margin-key G and is to be so operated whenever the platen is to be raised a short distance without being revolved-as, for eX- ample, when it is desired to widely separate two paragraphs or leave considerable blank space intermediate of the top and bottom of the sheet being type-written. In such cases all that is done is to depress the said platenraising key F and repeat this action until the platen is raised to the desired height, according to the required space to be left on the said sheet between the lines of type-writing. Each depression of the key F will raise the platen the space of either a line or two lines, according to the position of the described cam-head U2 at the time.

When the sheet of paper is fully type-written upon or otherwise completed, it may be readily removed from the machine as follows: The operator places his left hand on the handwheel F2 and depresses the finger S2 with his other hand, so as to control the ascent of the platen, just as described hereinbefore, when putting the paper on the platen. When the latter is raised to the required height, he removes his left hand from the hand-wheel and his right hand from the finger' S2, and now takes hold of the hand-wheel F2 with his right hand and with his left hand presses the pushrod A3 against the adjacent end of the lever L3, which turns said lever on its pivot f4, thereby withdrawing dog 7a4 from engagement with the teeth or notches of wheel O3, and in order to prevent the lever being drawn back by the spring K3, so that the dog would again engage, the hereinbefore-named pivoted latch x3 is dropped into the notch w3 in said pushrod A3. When these parts are thus held against movement, the operator begins to turn the platenJ in the opposite direction from that employed in feeding the sheet of paper IDO lIO

to said platen, and as said sheet begins to emerge from its position between the platen and the open annular paper-clamps vI)2 D2 he grasps said sheet with his left hand, meanwhile continuing to turn the hand-wheel F2 and platen with his right hand, and thus quickly completes the said removal. As soon as the paper is removed the'push-rod A3 must be freed from the latch at, so that the dog 7a4 may be again thrown into engagement with the notched or toothed periphery of the wheel O3.

One great advantage of my machine is the fact that the' platen is always revolved in one direction, and hence there is no time lost in carrying the platen back from the end of one line to the beginning of the next, as in the,

case of the ordinary machines with horizontally-disposed platens.

19. In atype-writin g machine, the combination -with a horizontally-disposed keyboard and vertically-arranged platen, and suitable supporting-frames therefor, of a pair of bellcrank shift-levers pivoted, one on each side, to the side pieces of the upper part of the frame or casin g on the inner sides thereof; a shift-key on one side of the keyboard; a retracting spring connecting the shift -lever with the side piece of the frame on that side; stops or pins projecting inwardly from the side pieces of the frame, on both sides, to limit the backward movement of the shiftlevers; posts projecting obliquely forward from each shift-lever and vconnected by a transverse bar having right-angled ends projecting rearwardly; an arc-shaped rod connectingthe upper ends of the long arms of the shift-levers; a series of type-bars pivotally arranged on said rod and having 0bliquely-disposed feet projecting downward and rearward beyond said rod; a transverse shaft j ournaled in the sidepieces of the frame; key-levers connecting said transverse shaft with the type-keys of the keyboard; links connecting the feet of said type-bars to the said key-levers; a shift-key lever on one side of the frame connected .at its forward end to the lower end of the shift-key and at its rear end to the said transverse shaft; another shift-key lever on the opposite side of the frame, connected at its rear end to said transverse shaft, and at its forward end pivotally connected by a link to the short arm of the bell-crank shift-lever on that side, and another link similarly connecting the other bellcrank shift-lever with the other shift-key lever.

20. In a type-w ritin g machine, the combina- IOO IIO

tion with a suitable frame or casing and a bell-crank shift-lever pivotally connected thereto, and type-keys and levers, and typebars pivotally connected together and to said shift-lever; of a retractingspring connected to the long arm ot' said shift-lever and to said frame or casing; a locking-cam rigidly secured to one end of a shaft journaled in the adjacent side piece of said frame or casing above and in vertical line with the short arm of said shift-lever; and a iin ger rigidly secured to the other end of said shaft, said cam and linger projecting at practically right angles to each other.

2l. Ina type-writingmachine, the combination with a horizontally-disposed keyboard and a vertically-disposed plate-n, and series of type-keys, key-levers, shift-key and shiftkey levers; of a pair of bell-crank shift-levers; an arc-shaped rod connecting the upper ends of the long arms of said shift-levers; and a series of type-hars pivotally arranged on said rod and linked to said key-levers, the free ends of said type-bars each bearing two printing characters, slanting in opposite directions from the center of said ends, whereby, when any one of said type-bars makes impact against the platen, the character struck will always stand exactly vertical and give a direct horizontal impression,wl1ether the said i type-bar' is in its normal or shifted condition.

22. Inatype-writing machine, the combination with a horizontally-disposed keyboard and a vertically-disposed platen, of vertical standards on each sideof said platen,said standards having vertical grooves therein,

and being united, near their upper ends, by'

a yoke-shaped cross-piece; a platensupporting slide, having side bars adapted to move vertically within the said grooves inthe y standards, and united by upper and lower cross-bars, between which the said platen is supported, and one of said side bars having a vertical series of teeth or notches; a vertically-movable shaft extending entirely through the center of said platen and through the said cross-bars, and so secured to the platen that the latter is capable of moving freely up and down on said shaft, but incapahle of revolution independently of said shaft; a line-spacing mechanism having dogs in adjustable engagement with the toothed or notched side bar; and means for automatically elevating the platen and supportingslide on the withdrawal of one of said dogs from its contact with said side bar.

23. In a type-writing machine, thecombination with a horizontally-disposed keyboard, a vertically-disposed platen, and-typebars arranged to present the type vertically to the ranged to present the type vertically to the platen, of a single key and connecting mechanism, for automatically raising theplaten at the termination of each line and simultaneously revolving said platen the required inarginal distance for the beginning of the next line, so that said platen is continuously and successively revolved in one direction only, from start to nish of the sheet being written upon, and with each line beginning at the predetermined distance from the edge of the said sheet, by the successive depression of the different keys only.

25. In atype-writing machine, the combination with a horizontally-disposed keyboard and a vertically-disposed platen, of a marginregulating key for automatically raising said platen and beginning each new line at a stated distance from the edge of the sheet being written upon, and adjustable means for predetermining the said distance as desired, said platen being continuously revolved in one direction' only, without lateral change of position of said platen.

26. In a type-writing machine, the combination with a keyboard having type-keys and lea vers, and a series of type-bars and a platenraising key, and connecting mechanism; of a vertically-disposed platen,supported on a ver tically-movable frame, and movably mounted' on a vertical shaft; and another vertical shaft carrying two horizontally-disposed shell pulleys, each containing a volute spring ar .ranged to revolve said pulleys in opposite directions,onc of said shell-pulleys being geared to the lower end of the first-named vertical shaft so as to automatically revolve said platen witheach depression of a type-key, and the other shell-pulley being connected by cord and .pulleys to the said platen-supporting frame, so as to automatically raise said platen with each depression of the platen-raising key. In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses;
